Common year starting on Friday

From Simple English Wikipedia, the free encyclopedia

This is the calendar for any common year starting on Friday, January 1 (dominical letter C). Examples include 1971, 1982, 1993, 1999, 2010, 2021, and 2027 in the Gregorian calendar,[1] or 2011 and 2022 in the Julian calendar. This common year is one of the three possible common years in which a century year can begin on, and occurs in century years that yield a remainder of 100 when divided by 400. The most recent such year was 1700 and the next one will be 2100 in the Gregorian calendar (see bottom tables).

In this common year, Martin Luther King Jr. Day is on January 18, Valentine’s Day is on a Sunday, Presidents Day is on its earliest possible date, February 15, St. Patrick’s Day is on a Wednesday, Mother’s Day is on May 9, Memorial Day is on its latest possible date, May 31, Father’s Day is on June 20, Independence Day is on a Sunday, Labor Day is on September 6, Columbus Day is on October 11, Halloween is on a Sunday, Veterans Day is on a Thursday, Thanksgiving is on November 25, and Christmas is on a Saturday.

This is one of three common years to have only one Friday the 13th, the other two being Common year starting on Wednesday and Common year starting on Saturday. The Friday the 13th in this common year is in August. This characteristic is shared with Leap Years Starting on Thursday but also have another one in February.

A common year is a year with 365 days, i.e., not a leap year.
